Fire Detection and alarm systems help detect fire in the nascent stage and suppress and control it before the fire risks get out of control. These systems help save precious lives by alerting the occupants of buildings in time. They also allow evacuation if needed. Fire companies can mobilize their personnel and are alerted by these systems so that firefighting teams can reach the emergency location in time. These systems have several main functions. They can help identify developing fire through sensors or other devices; they alert building occupants to a fire risk. These systems also alert the fire department control room. These systems can shut down other systems for example HVAC, electrical, etc., and activate fire suppression systems.
Fire Control Panels
These panels act as the “brain” of the fire alarm system. It monitors various “input” devices of the system, such as flame detectors, heat sensors. If triggered, it activates output devices such as bells, warning lights, emergency dealers, and building controls.
Conventional Fire Control Panel
In conventional systems, a protected section of the building is monitored by various detection devices, like flame detectors, heat sensors, and call points connected to the panel through single or multiple circuits. Usually, different types of devices connect to circuits; several fire risks and hazards are covered depending on the nature and conditions of the building, its use, its contents, and its occupants. Fire fighting contractors that provide different Fire alarms and detection systems can provide complete details about different types of heat, flame detectors, and better assessment for the types of input devices suitable for your premises.
Conventional Fire Alarm System
In case of a fire incident, the detectors trigger the mechanism to close the circuit; the fire control panel recognizes this as an emergency condition.
The control panel then activates signaling circuits to sound alarms and request emergency services. Conventional systems are relatively simple and easy to service. These systems need extensive wiring, which is a disadvantage if you need to install conventional alarm systems in large buildings.
Addressable Fire Control Panel
Addressable or Digital systems are sophisticated fire detection and alarm technology. All input and output devices are controlled by microprocessor and system software; this enables the system to give a swift and desired response in case of emergency.
Addressable Fire Alarm System
In the addressable system, the initiating device is identified with an address. This address is programmed into the control panel’s memory. This address includes information regarding the type of device, device location, and response programming like which output device to use in case of emergency.
The thermal detectors are fixed temperature devices that are activated when a protected area reaches a certain preset temperature range (57°–74°C). The other widely used thermal sensor is the rate-of-rise detector, which detects fast temperature climbs over a short period. The thermal detector and rate of the rising detector are both “spot type” detectors, on a ceiling or a wall at uniform distances in between. The fixed temperature line type detector consists of two cables. An insulated sheathing designed to break down during heat exposure. Thermal sensing capacity can be enhanced in the line type detectors in comparison to spot type detectors. Because detector density can be increased without incurring heavier costs. They don’t give fake alarms. Their disadvantage lies in their ability to activate alarm until room temperatures go beyond a threshold range. At this point, however, the risk factor has the potential to get out of control.
Fire fighting contractors don’t rely on a single type of fire detector, they used different types of detectors in different conditions and settings to maintain acute sensitivity and fire detection ability without raising fake alarms. Smoke detectors are a newer technology, they became a popular choice for residential buildings where high levels of protection and life safety standard are required. These devices can identify a fire while in its smoldering or nascent stage. These spot-type devices’ placement pattern is similar to spot thermal units.
To keep the fire alarm system in perfect working order; Fire maintenance is critical to keep your installations in perfect working order, different facilities and establishments sign AMC for the fire system. In this way, your system is under the direct supervision of qualified and expert personnel who can keep your fire system efficient and reliable and ensure compliance to safety regulations is cent percent.
